4, Fig. 2, binder-shaft.

5 is the arm of the compressor, hinged at one end to the ear 4 andhaving adjustably is an ear formed on the hub of the secured to it neartheother end the compressor 6.

7 is a link pivotally secured atone end to the arm 5 and at the otherend to the free end of the crank 8 on the compressor-shaft 9, which isjournaled in suitable bearings below the binding-platform and hassecured to its free end the crank-lever 10, as shown in Figs. 3, 4., and5.

12 is a connecting-rod pivotally secured at one end to the arm 11 of thecrank-lever and at the other end to the compressing-lever 13, which isfulcrumed at 14 to the frame, and is provided at its free end with theanti-friction.

roller 15, which is adapted to travel on the compressing-flange 16 ofthe sprocket-Wheel 17. The sprocket-wheel is secured upon the shaft 18,which actuates the knot-tying mechanism, and is journaled in theoverhanging arm of the U-shaped frame 19, rigidly se-- cured to thebinder-frame and for the pur pose of supporting the binding mechanismabove the binding-platform, as in the ordinary construction of binders.

Below the binding-platform is suitably journaled in the frame of thebinder the packer-shaft 20, which actuates the packers 21 by means ofsuitable cranks 22 and 23 in the well-known manner. This packer-shaftderives its motion by suitable driveconnection with theharvester-gear-as shown, for instance, .in the drawings, wherein 24,Fig. 3, is a sprocket-wheel on the packer-shaft, and 25, Figs. 2, 3, and1], a sprocket-wheel on the shaft 26, which actuates the cutter-bar ofthe harvester and which derives its motion by suitable intermediategearing from the drivewheel 27 of the harvester. A chain 28 transmitsthe motion from the sprocket-wheel to the sprocket-wheel on thepacker-shaft.

The front end of the packer-shaft carries a sprocket-pinion 29, whichforms the loose member, and the cross head 30 the fast member, of aclutch, which is constructed, preferably, as shown in detail in Figs. 5,6, and 7, and wherein 31 are pins carried by the fast member 30 andadapted to normally engage with the arm 32 of the dog 33, which latteris pivotally secured at 34 to the loose sprocketpinion 29. This dog hasan arm 35, which normally rides on the hub of the sprocketpinion, andalso an arm 36, which projects outwardly and is adapted to strike in therevolution of the packer-shaft the tripping-lever 37 when the latter isin the position shown in Figs. 3 and 5 and thereby trip the clutch.

The tripping mechanism, of which the tripping-lever 37 forms a part, isconstructed and arranged as follows: The tripping-lever 37 is pivotallysecured at 38 below the end 'of the binder-shaft, and carries the dog39, which at its free end is provided with a shoulder 40, on which thearm 42 of the crank-1e ver 10 engages when the binding mechanism isthrown out of gear, as shown in Fig. 5. The trippingarm is furtherprovided with the heel-extension 50, which is adapted to be depressedduring the operation of the binding mechanism bya cam 49 on thebinder-shaft. A spring 41 bears with its tension against the free end ofthe tripping-lever, and this spring is preferably sleeved upon a rod200, which slid ingly engages near one end into a guide-bearing 201 onthe tripping-lever, and near the other end into a similar guide-bearing202 on the binding-frame, and has an adjusting-nut 203 secured upon it.In connection with this red an arm 204 is placed on the needle-shaft,which arm bears, during a certain period of .the operation of thebinding mechanism, against the free end of the rod 200, whereby thespring 41 is compressed, for the purpose hereinafter more fullydescribed.

The crank-lever 10 is loosely sleeved upon the free end of thecompressor-shaft 9, and has formed upon its hub a circular segmentalflange 43. The portion of the com pressorshaft projecting beyond thiscrank-lever is squared and has sleeved upon it the thimble 44, whichalso has a corresponding circular segmental flange 45, similar to theflange 43 ofthe crank-lever, as hereinafter described. A little crank 46is secured upon the outside of the compressor-shaft to secure the partstogether and form means of attaching one end of the compressor-spring47, which is coiledaround these parts, and has its other freeend-secured to the pin 48 on the cranklever.

V. The parts being thus arranged,as described and shown, they areintended to operate as follows: The crank-lever 10 forms the loosemember of a clutch, while the thimble 44 and the crank 46 together formthe fast member, the latter being made in two pieces for the purpose ofadjusting the tension of the spring to any desired degree by merelychanging the position of the crank 46 on the squared end of thecompressor-shaft. The segmental circular flanges 43 and 45 on the looseand fast members, respectively, of the clutch, permit a limited playbetween the two clutch members for the purpose of tripping the clutch onthe packershaft and compressing the bundle, as hereinafter described.The compression-flange 16 forms avariable abutment for the loose memberor crank-lever 10. In operation the pressure of the grain against thecompressor-arm istransmitted to the compressor-shaft 9 in the directionof the arrow shown in Fig. 10. This carries the thimble 44 and crank 46in the same direction, and through the medium of the compressorspringthe crank-lever 10 is carried'in the same direction. Thisbrings thepressure of the grain to bear against the shoulder 40 of the dog 39 onthe tripping-lever. This tripping-lever resists the pressure by thetension of the spring 41; but as this spring is inferior to thecompressor-spring it will be compressed and the tripping-lever 37 belifted out of interference with the dog 33 of the tripping-clutch of thepacker-shaft, which clutch Will immediately serve to start the bindingmechanism.

The retripping of the clutch during the prescribed interval in which thebinding mechanism has to operate is prevented by the cam 49 on thebinder-shaft, which is adapted to bear against the heel-extension 50 ofthe tripping-lever, as shown in Fig. 4, when the needle has risen toencircle the bundle. The motion 'is carried from the packer-shaft to thebinding mechanism by means of the chain 51, Whichpasses aro und thesprocket-wheel17 and idler-pinion 52 at an angle to engage with thepinion 29 on. the packer-shaft, as shown in Figs. 3, 4, and 5.

The lower course of the chain, which may be provided with any reasonableslack, is guided below the upper course of the chain by means of thecurved guiding-flange 53, which is secured below the pinion 54 from thestub-shaft 55 of the idler-pinion, and to per.- mit a proper adjustmentof the chain the idler-pinion 52 is adjustably secured in position tothe binder-frame in any suitable manner. The motion of the packer-shaftbeing in the direction shown by the arrows in Fig. 4 is therebytransmitted to the shaft 18, which actuates the knot-tying mechanism inthe reverse direction. Motion is communicated to the binder-shaft bymeans of a crank 56, secured upon the front end of the binder-shaft, anda connecting-rod 57, connected with the wrist-pin on sprocket-Wheel 17.

The compression of the bundle is produced by the operation of thecompression-flange 16, which, during theproper portion of the revolutionof the sprocket-wheel 17, forms an abutment for the anti-friction roller15 on the compressing-lever, and through the connection described locksthe crank-lever 10 in place, so that the pressure of the grain againstthe compression-arm, as produced by the pressure of the binder-arm inencircling the bundle, has to be taken up or resisted by thecompressor-spring, which is free to contract on account of the playbetween the loose and fast members of the clutch between which it issecured.

To permit the free operation of the tripping mechanism, thecompression-flange 16 is provided with the depression at itsstart-ingpoint, which at the normal position of the binding mechanismallows a limited free play to the compressing-lever 13. Thetrippinglever 37 is held in its normal position, as shown in Fig. 5, bythe spring 41, which at one end presses against the guide-bearing 201 onthe tripping-arm 37 and with its other end against the adjustable nut203 of the sliding rod 200, which latter at its free end passes throughanother guide -bearing 202 and rests against the oscillating arm 204,carried by the needle-shaft. The tension of the spring through themedium of the tripping-lever 37, dog 39, arm 42 of crank-lever 10, andshaft 9 holds the compressor forward against the grain until the bindingmechanism is tripped into gear.

To permit the ejectors to withdraw the bundle when completed, thecompressor-arm has to be withdrawn below the platform. This isaccomplished by the compressor-flange 16 turning abruptly at 61, thusdepriving the crank-lever 10 of its abutment and rendering thecompressor-arm free to withdraw below the platform. The compressor-armis restored to its normal position bythe eccentric portion 121 of thecompressor-flange, and the stop 120 on the crank-lever 1O strikesagainst the binder-frame and arrests the crank-lever 10 in its propernormal position, while at the same time the tripping-lever 37, beingfreed from the action of the cam 50 on the bindershaft, drops intonormal position under 'tension of the spring 41. lVhile thetrippinglever 37 drops back into its normal position, Figs. 3 and 5, thearm 204 pushes against the end of the rod 200, and thereby increases thetension of the spring 41, which thereby enables the tripping-lever 37 towithstand the shock of the dog 33 in striking against it much betterthan if the tension of the spring 41 were allowed to spend itself whilethe tripping-lever 37 drops into its normal position, and thus becomestoo weak to firmly hold the tripping-lever against the face of,

the dog 33 in the act of tripping the clutch.

At the front end of the binding-platform is mounted 'the end board 62,which forms a butting device for the known operation of butting thegrain upon the binding-platform, and to this end it is provided with thefollowing mechanism: the arm 63, which consists of two bars rivetedtogether and pivotally secured at 63 to the binder-frame, so as to swingin a plane parallel with the bindingplatform. The lower end of this armslid-' ingly engages in a slot of the roller 64, which is journaled nearthe lower end of the butter, as shown in Fig. 13. Near the upper end ofthe butter is secured the bracket 65, which engages upon the crank 66,to which motion is communicated by intermediate gearing from anysuitable part of the operating mechanism of the harvester, preferably asshown in the drawings, wherein 67, Figs. 3 and 12, is the shaft of oneof the rollers over which the elevating-aprons pass, which, as in theusual constructions, elevate the grain onto the binding-platform. Thisshaft is extended through the binder-frame and carries on its free endthe bevel-pinion 68, which engages with the bevel-pinion 69, whichdrives the crank 66, thereby imparting an oscillating motion to thebutter. To adjust the butter laterally upon the binding-platform, alever 7 0, extending in proximity to the drivers seat, is pivotallysecured at 71 to an upward extension of the arm 63.

Upon the inner end of the shaft 18, which actuates the knot-tyingmechanism, is sleeved the upper end of a knotter-frame 72, the lower endof it being secured to the breast-plate 73, which latter is securedabove the binder-plat,- form and is of the ordinary construction, exceptas hereinafter described, The frame 72 carries the knotter,whichconsists of the billshaped knotter-head 74, mounted upon the end of theknotter-shaft 75,which is journaled in the frame 72 and carries on itsfree end the knotter-pinion 76.

77 is a movable jaw, which is slidingly secured in the knotter-head bymeans of the shank 78, sliding in a suitable slot formed in theknotter-shaft, and, projecting beyond the knotter-shaft, engages withits free end the lever 7 9. This lever 79 is pivotallysecured at 80 tothe knotter-frame, and carries upon its free end a roller 81, and isconnected to the tensionrod 82, which carries the tension-spring 83. Theknotter-pinion is cut awayat its innerend, as at 85, to form a fiat faceor delay-shoe, which is adapted to prevent the rotation of theknotter-pinion while traveling in contact with the delay-flange 86 ofthe cam-wheel 87, and the knotter-pinion also carries the mutilatedpinion 88, which has two teeth only.

To the knotter-frame is pivotally secured at 89 another frame 90, whichcarries the oscillating twine holder, which is constructed as follows:The frame 90 carries at its free end the ring bearing 91, in which thenotched annulus 92 is loosely seated and adapted to revolve around itscenter. This annulus is provided upon its inner edges with the notches93 and upon its upper face with the cogs 94, which are adapted to meshinto the cogs of the mutilated pinion: 88 when the parts are brought incontact, as shown in Fig. 18, by the swinging of the twine-holder towardthe knotter. A-notch 95 is cut into the ringbearing 91 of the frame, andnotches 96 are cut in the outer periphery of the annulus. They are outbetween the teeth at intervals of three teeth. 97 is a shoe pivotallysecured at 98 (see Fig. 23) to the ring-bearing 91. This shoe isprovided upon its inner end with the groove 99, which loosely engageswith the inner edge of the notched. annulus and is held in engagement.therewith by means of the spring 100, secured to the shoe and hearingwith its free end against the set-screw 101, by which means the tensionof the spring can be adjusted. A knife 102,provided with thecutting-edge 103, is secured on top of the shoe, whereby the twine whichis engaged in the notch nearest to the cutting edge of the stationaryknife is necessarily forced against the cutting-edge whenever theannulus makes its partial revolution. The frame 90, which carries thetwine-holder, is provided with the arm 104, which carries at its freeend the roller 105, and with the stop 106. The cam-wheel 87 is securedto the inner end of the shaft 18 and is provided with the rim 107, whichengages into the notch 95 of the twineholder and thereby locks theannulus of the twine-holder in position. A portion of this rim is cutaway at 108 for the purpose of unlocking the annulus, as will behereinafter described in the operation. The side of this rim forms thedelay-flange 86, which, as before described, travels in contact with thedelay-shoe 85 of the knotter-pinion, except where such rim is cut awayto unlock the knotter-pinion, and at this interval the camwheel isprovided with the cogs 109, which are adapted to engage with theknotter-pinion to impart two complete revolutions to said knotter-pinionin one revolution of the camwheel. The cam-wheel is formed with aninterior cam 110, upon which the anti-frictionroller 81, which controlsthe movable jaw,

travels. Another interior cam 11]. is formed within the dished orconcaved portion of the cam-wheel, by which the anti-friction roller 105of the twine-holder frame is controlled, for the purpose of oscillatingthat frame to impart to it an oscillating movement toward the knotter ata certain stage in the operation of tying the knot, as shown in Fig. 18,while the stop 106 normally rests against the hub 112 of the cam-wheeland thereby holds the twineholding frame in the position shown in Fig.19. The breast-plate 73 is provided with the slot 113, through which thebinder-arm is free to move in and out of position. Near the lower end ofthis slot the breast-plate is provided with a horn 114, which projectsfrom one side of the slot to the opposite side, but does not come incontact therewith, but projects above. In proximity to the lower end ofthis slot is pivotally secured to the breastplate at 115 theoscillating-lever twine-guide 116, one arm of which is provided with theincline 117, while the other arm is provided with the horn 118, which isadapted to close the lower end of the slot 113 in the breastplate belowthe horn 114 in the position of said twine-guide shown in Fig. 17.

Having now described the construction of the knot-tying mechanism, Iwill now proceed to describe the operation of the whole bindingmechanism.

The grain being delivered in the usual manner upon the binding-platformby the elevating devices, the packers feed it down against thecompressor-arm, which is then in the normal position shown in Fig.3. Atthe same time the butter operates against the butt-end of the grain andassists the packers to feed it and also to collect it in regularorder,being adjusted by the operator bymeans of the lever 70, accordingto the length of the straw. The pressure of the grain is brought to bearfrom the compressor-arm through the medium of the crank-lever 10 againstthe dog 39 and tends to lift'up the tripping-lever out of its normalposition, in which it holds the clutch on the packer-shaft tripped. Assoon as a large enough bundle is collected and the pressure against thecompressor-arm is sufficient to overcome the tension of the spring 41(which holds the tripping-lever in its normal position and which may beadjusted for greater or lesser pressure) the tripping-arm is lifted upout of engagement with the dog 33 of they tripping-clutch. Immediatelythe clutch is perfected, and the movement of the packer-shaft isimparted to the sprocket-pinion 29 of the packer-shaft, which transmitsit through the medium of the sprocket-chain 51 to the sprocket-wheel 17,which imparts motion to the knot-tying mechanism through the shaft 18,and at the same time oscillates the binder-arm on the binder-shaft 3.The movement of the latter shaft carries the cam 49 down against theheel of the tripping-lever, and thereby prevents the retripping of theclutch during the operation of tying the bundle. As the binding-armmoves into position for binding, the anti-friction roller 15 on thecompressing-lever rides on the compression-flange 16, and thereby locksthe crank.- lever 10 in position. Therefore the strain of the bundleagainst the compression-arm is resisted by the tension of thecompressorspring 47, and the compression of the bundle is thereforegoverned bythe tension of the spring, which may be increased or lessenedby adjusting the crank 46 in a different position upon the squared endof the compressorshaft. By making the segmental flange 43 and 45 eachabout one-quarter of a circle, as shown in the drawings,it will be seenthat there is a play of about one-half a circle in which the tension ofthe compressor-spring can be made effective to compress the bundle. The

shoe 97.

cam-wheel 87 releases the delay-shoe on the knotter-pinion, and the cogs109 on the camwheel engage with the knotter-pinion to impart to theknotter two revolutions, during which the loop upon the knotter-head isformed, as in the usual manner. During the same interval the roller 81011 the lever '79, which controls the movable jaw, rides over theinwardlyprojecting portion of the cam 110 011 the cam-wheel, and therebythrough the connections described opens the jaw of the knotter, at theproper moment, as shown in Fig. 20, to receive the ends of the twine.The cam 111 strikes the roller 105 of the twine-holding frame andoscillates it toward the knotter, as shownin Fig. 18. At the same timethe cut-away portion of the rim of the cam-wheel, unlocking the annulus,permits the two teeth of the mutilated pinion to impart to the annulus apartial revolution, which carries that portion of the twine engaged intoa notch of the annulus between the annulus and the shoe and thereby nipsit fast, while at the same time the knife severs the band, which is nowcompletely tied around the bundle.

The oscillating movement of the twineholder toward the knotter provides,also, the necessary slack in the twine for tying the bundle. As thebinder-arm withdraws after the knot-tying is complete, the twine, beingnipped fast on its end by the twine-holder, is drawn through thebinder-arm and placed in position and across the binding-platform readyfor the next bundle, as in the usual operation of the knot-tyingmechanism.

The twine is prevented from slipping off the knotter-head by the horn114 in the breastplate; but the'rotary movement of said knotter-headdisengages it at the proper time from said horn and lets it drop ontothe horn 118, which is held in the position shown in Fig. 17 by thebinder-arm impinging against the inclined face 117 of theoscillating-lever twine-guide. As soon as the binder-arm is withdrawn toits normal position the horn 118 of the oscillating-lever twine-guide isfree to move out of the way to release the band, and the bundle isthrown off by the ejectors 119, which have now moved in position. One ofthe ejectors is preferably secured to the cam-wheel and the other to theactuatingshaft 18 of the knot-tying mechanism. The power exerted by theejectors against the bundle strips the knot off the knotter-head andtightens it. After one revolution of the shaft 18 is completed all theparts are again in their normal position, and the trippingclutch hasbeen tripped to discontinue the movement until a fresh bundle isgathered upon the platform.
